JSON e and JSON E

json, scientific-notation

Solution

It's the notation JSON (and most programming languages) use for scientific notation. Scientific notation is used to denote very large or small floating-point numbers. The `e` (or equivalently `E`) is equivalent to "×10^". For example,

`3.7e-5` = `3.7E-5` = 3.7×10-5 = 0.000037

Positive or negative exponents may be used, and in the case of positive exponents, the `+` symbol may be omitted:

`6.02e+23` = `6.02e23` = 6.02×1023 = 602 sextillion

More details are available at the Wikipedia article on scientific notation.

Problem

On the JSON website here, it explains the different possibilities of JSON 'objects'. However, in the numbers section, these appear: `e` | `e+` | `e-` | `E` | `E+` | `E-` 1 - What do these represent? In searching for an answer, `<E>` appears alot. 2 - Is `<E>` related to the above `e`|`E`s?
